Klingspor SMT 524 AC 5" Flap Disc - 40 Grit

SMT 524 AC ACCU - abrasive mop disc for stainless steel and steel

The abrasive mop disc SMT 524 AC ACCU is intended for work on the following materials:

• steel and
• stainless steel.

SMT 524 AC ACCU - the abrasive mop disc for battery-powered angle grinders

This allrounder is an equally excellent option for surface grinding and work on edges. The backing plate made of a glass fibre comes with a convex shape. The convex allows the tool to make point-by-point contact on the workpiece and achieve a higher removal rate than would be possible with a flat plate. The abrasive grain made of zirconia alumina combines high stock removal performance with outstanding service life.

Also suitable for high-speed machines

The special arrangement of its abrasive flaps allows this allrounder to also excel on stainless steel when used in combination with cordless grinders. The grinding particles made of zirconia alumina self-sharpen throughout grinding. This ensures continuous stock removal throughout the entire lifetime of the abrasive mop disc.

This is how you use the SMT 524 AC ACCU safely

Naturally, the abrasive mop discs by Klingspor comply with safety standard EN 13743 and oSa guidelines. Not only that, but they actually exceed them. Nevertheless, there are a few things the user needs to concider when working with cordless grinders. Clearly indicated on every abrasive mop disc is its maximum permissible circumferential speed. Also imperative is the maximum permissible speed of the cordless grinder, which is tied to the circumferential speed and specified in revolutions/minute.

You should strictly adhere to these speed limits

Before you fit the abrasive mop disc check and inspect before fitting it. Any signs of damage, then you must not use. There is a risk of it breaking during use or of you becoming injured by fragments flying about. You also need to refrain from working in the vicinity of combustible materials. Sparks quickly start flying during grinding on steel or stainless steel. When working with a cordless angle grinder, always wear protective glasses, a dust mask and ear protection. Work gloves are also part of personal protective equipment

• The abrasives used have also been engineered to work with high-speed angle grinders (80 m/s) and are designed to offer a wide range of possible applications. The optimised arrangement of the grinding flaps ensures first-rate grinding performance, long service lives and optimised utilisation to the end
• The cloth flaps are coated with zirconia alumina, ceramic or aluminium oxide and spaced equally on the backing plate. The optimised cloth-reinforced backing guarantees the operator a fresh grit and, thus, consistent removal throughout the entire work process
• The backing plates included in our SMT range are made of glass fibre or glass-fibre reinforced plastic. They are extremely hard-wearing and deliver optimal power transmission to the work piece
• A special manufacturing process ensures an exceptionally strong bond between baking plate and grinding flaps and produces a level of break resistance that easily exceeds the provisions of the oSa and EN 13743 standards
